No big changes from the original. Just added some stuff.

• bevelling for screw the holes
• generate more brackets in one go (grid layout)

In the scad file there are the following additions:
bracketNumberY number of brackets on the y ax
bracketNumberX number of brackets on the x ax

so when you need 6 bracketNumberY = 2 bracketNumberX = 3 for example, duh ;)

brackedSpacingY brackedSpacingX u can use so that the object do not overlap

bevelledHoleDiameter is used for the diameter of the screw-head that U may what to use.
bevelledHoleHeight is the height of the screw-head
